wINDow REGULATOR Filed Nov. 3, 1928 5 Sheets-Sheet 3 Patented Aug. 12, 1930 PATENT OFFICE PETER O. BORGESON, F MIAMI, FLORIDA WINDOW REGULATOR Application led November 3, 1928. Serial No. 317,076.

This invention relates to window regulators, and more particularly designed for application to closed automobile bodies, such as coups, sedans and the like, and, it is a distinct and practical improvement to overcome certain practical objections to, and defects in, the type of regulator now used for raising and lowering the windows of motor vehicle bodies. y

A further object of my present invention is the provision of a window regulator comprising a peculiar arrangement of levers situated in the wall of the window and which can be easily and quickly actuated by the movement of a handle lever in a short arcuate path for completely lowering or raising the window or partially lowering or raising the same.

A still further object of the invention is the provision of a positivelock for retaining the window at any desired-elevation.

With the above and other objects in view,-

the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claim hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar partsthroughout the several views:

Fig. 1, is an inside elevation of the window regulator, showing the levers in two positions, the full lines indicating the position ofthe levers when the window is fully raised and the dotted lines indicating the position of the levers when the window is fully lowered.

Fig. 2, is an inside elevation of the window regulator, more clearly showing a part of the levers in the position they assume when the window is in its raised position.

Fig. 3, is an inside elevation ofthe window regulator more clearly showing a part of the levers in the position they assume when the window is in its lowermost position.

Fig. 4, is a detail in inside elevation of the means for actuating the levers and locking the window at a predetermined elevation.

Fig. 5, is an outside elevation thereof.

Fig. 6, is an outside elevation of the lever actuating means, the same being shown as havingy been manipulated to unlock the window and to permit the window to be lowered by further movement of the handle lever in the same direction as it is slanting.

Referring to the accompanying drawings, the reference character l represents a vehicle door which is provided with a suitable crosspiece 2 upon the inner side of the door and the numeral 3 represents a sliding window l60 sash for a predetermined upper section of the door.

The reference numeral 4 represents a regulator supporting plate which is suitably fixed to the cross-piece 2 and covers a suitable cut- 65 laway portion of the cross-piece for accommodating the lever actuating mechanism shown in Figs. 4, 5 and 6 and which will now be first described.

The lever actuating mechanism comprises a strap member 5 provided at its upper end with an opening 6 for receiving a bushing 7 which is mounted upon a suitable pivot pin 8 which is suitably supported by the plate 4. Slidably mounted upon the lower end of the strap member 5 is a suitable sleeve 9 which is held upon the strap member 5 by means of a coiled spring 10 mounted in a slotted open ing 11 in the strap member 5 and by means of an outwardly directed pin 12 carried by 80 the sleeve and receivable in the slotted opening 11, as shown in Figs. 4, 5 and 6. The inner side wall of the sleeve 9 is provided with a plurality of suitable gear teeth 13 adapted to normally mesh with the teeth 14 of a seg- S5 ment gear 15 which is suitably fixed to the inner face o the regulator supporting plate 4, as clearly shown in detail in Fig. 4. The opposite or outer wall of the sleeve 9 has its upper edge provided with the V-shaped cam groove 16 adapted to receive for engagement the protuberance 17 at the lower edge of handle actuated strap member 18 which is provided intermediate its upper and lower ends with an opening 19 for receiving the bushing 95 7 upon which it is oscillatingly mounted. The lower portion of the strap member 18 is provided with a curved slotted opening 20 adapted for the passage therethrough of a suitable supporting pin 21 which is iXed at 100 its inner end to the strap member 5 intermediate the ends thereof, as shown in Figs. 5 and 6. Eachside edge ofthe strap member 18 is provided with an inwardly directed stop flange 22 to limit the Swingin movement of stra member 18 when manipu ated, as shown in Fig. 6, by means of a handle lever 23, which is provided with a slotted opening 24 to receive the bushin 7 and provided with a laterally directed pm 25 for reception in a suitable notch 26 in the upper edge of the swingable strap member 18, as shown in Figs. 4, 5 and 6.

The lever mechanism will now be fully described which is to be actuated by the mechanism just described for raising and lowering the window sash 2.

A lever 27 is pivotally connected at its outer end by means of a in 28 to a suitable bracket 29 which is fixe to the inner face of one of the side frame members of the door 1. The inner end of the lever 27 is suitably curved, as at 30, and pivotally connected, as at 31, to a sliding sleeve 32 mounted upon rail 33 which is supported below the sash 2 by means of the end connections 34, which are fixed to the lower rail 35 of the sash 2. An L-shaped strap member or ear 36 is pivotally connected to the lever 27 near the pivot pin 28 and is provided with an opening in one of its arms to receive the upper end of a` rod 37, the lower end of which is pivotally connected, as at 38, to an ear 39 fixed to the door 1 below the bracket 29. A coiled spring 40 encircles the rod 37 and is disposed between the ears 36 and 39. This sprlng 40 assists in raising the lever 27 by exerting its pressure thereagainst. The number 41 represents a lever which is pivoted at its lower end, as at 42, to the lever 27 approximately midway its ends. The upper end of straight lever 41 is pivotally connected, as at 43, to the outer end of a straight lever 44 which has its 'opposite end pivotally connected, as at 45, to a strap member 46 which is suitably fixed to the inner face of the cross-piece 2. A short lever 47 is pivotally connected at its lower end, as at 48, to the long straight lever 44 approximatel midway the ends of lever 44 and is pivota ly connected at its upper end, as at 49, to the curved end 50 of lever 51. Lever 51 is pivoted approximately midway its ends upon pin 52 which pin is fixed to the cross piece 2 and the plate 4. A lever 53 is pivotally connected at one end, as at 54, to the lever 5l and the opposite end 55 of lever 53, which is curved, is pivotally connected to the supporting pin 21 of the lever actuating mechanism.

The functions and the groupings ofl the variouslevers will now be described.

It will now be assumed that the window sash is closed or in its uppermost position and it is desired to lower the window. The operator irst raises handle lever 23 from the position shown in dotted lines A in Fig. 1, which position it assumes when not in use and causes pin 25 to be received in the notch 26 of strap member 18, as will be apparent from Fig. 4. This having been done, the operator now lifts up upon the outer end of lever 23 which causes the drawn from the -shaped cam groove by the slight arcuate movement of the strap member 18 through the movement of handle 23. The arcuate movement of member 18 causes the protuberance 17 to force the sleeve 9 downwardly thereby withdrawin the teeth 13 of sleeve 9 from mesh with t e teeth 14 of the stationary segmental ear 15. After the teeth 13 are withdrawn rom mesh with teeth 14,-which withdrawing movement is limited owing to the stop fianges 22, further movement of the handle lever 23 will cause pin 21 to move from position shown in full lines in Fig. 1 to the position shown in dotted lines, which is the extreme movement to cause the window to be completely lowered. This 'movement of pin 21 to which one end of lever 53 is connected will cause lever 51 to swing on pivot 52 to the position shown in dotted lines, which in turn, causes the short lever 47 to exert downward pressure upon the long straight lever 44 thereby causing lever connection 41 to exert downward pressure upon the long curved lever 27 pulling with it the window sash 2 through the sliding sleeve connection 32. The downward movement of lever 27 in an arcuate path, it will be observed, compresses the coiled spring 40 thereby generating force which can be expended against the lever 27 when raising the window thereby relieving the operator ofthe additional force that would be required on the handle lever to raise the window were the spring 40 not used.4 A reversal of the movement of handle lever 23, as above described, will cause the window to be raised.

Should it be desired to lower or raise the window but a Short distance, instead of all the way, the operator merely lets loose of the handle 23 and the coiled spring 10 will .cause the cam sleeve to raise, thereby forcing the protuberance 17 into engagement with the V-shaped cam groove which permits the teeth 13 to mesh with yteeth 14 of stationary segment gear 15, which will lock the window against downward displacement.

lVhen the window 3 has been raised to its uppermost position, the operating handle lever 23 will assume the position shown in full lines in Figs. 1 and 2. After the window has been raised to its uppermost, or closed.

position, the handle lever 23 is pulled outwardly so as to cause the pin 25 to be disengaged from groove 26, thus permitting the handle lever 23 to be swung to the horizontal position as shown by reference character A in dotted lines in Fig. 1.

When the window 3 has been lowered to rotuberance 17 to be with- 'Ill its lowermost position, the lever 23 will assume thev position shown in dotted lines B in Fi 1, from which position it is then move to the position shown in dotted lines re resented by the reference character A.

en the handle lever 23 is in its horizontal position, as shown in Fi 1, and designated A, it will be observed' t at it is out of the liga of the arm of the occupant of the vevIn Fig. 1 of the drawing, I have broken away a part of the cross piece 2 and have omitted plate 4 and the stationary segment gear 15 so as to more clearly see the position of the levers when-in their uppermost position. v

From the fore oing description, it is evident that I provide a window rellator for the windows in vehicle doors whic is strong and durable, easily operated and which will prove highly-eilcent for the purpose intended.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not wish to be understood as having limited myself to the details of construction shown and described,- but desire to have it understood that the invention I have shown in the drawings is merely illustrative, as it ismanifest that various minor changes may be made in the exact construction and particular arrangement of parts without departing from the spirit of my invention, hence I reserve the right to make any such changes,

or modifications as may fairly fall within the scope of the appended claim when fairly construed. v

What I claim is:

In a window regulator structure, a supporting plate, a lever pivotall)7 connected at one end to a door frame, a sliding sleeve connection between the opposite end of said lever and a window sash, a toggle joint connecting said lever with said plate, a rocking lever pivoted intermediate its ends to said supporting plate, a connection between one end of said swinging lever and said rocking lever, lever actuating means pivotally supported by a supporting plate, a connection between the opposite end of said rocking lever and said lever actuating means, and a handle for imparting movement to said lever actuating mechanism for raising and lowering the window sash.

In testimonywhereof, I have hereunto signed my name to the specification.
